In the present study, a new method for searching all exit parameters of the thermoelectric module has been realized. The new method is based on measurement of thermo-emf of a working module and comparing the results obtained with those of classical methods. The new method is used for investigation of the values of par…
Abstract The wettability of PLLA substrates was modified by plasma copolymerising on its surface thin films based on EA and HEA. The composition of the reactive gas inside the plasma chamber was that of the corresponding liquid mixture of the comonomers. The surface of the substrates was investigated by AFM, which sho…
The self-assembly kinetics of a peptide-block-poly(n-butyl acrylate) copolymer (pnBA-(TV){5}{switch}nFGconjugate) in solution and the blend behavior of the resulting fibrillar nanoobjects are investigated. By using a switch peptide segment with temporarily suppressed aggregation behavior, the solution self-assembly of…
We would like to correct the following statement “All previous reports on particle-stabilized emulsions deal with emulsions that have internal phase levels below 70 vol %.” made in the introduction of our recent article. Since the publication of our communication, three papers1–3 describing Pickering w/o and o/w emuls…
Thin metal films show a residual transmission for light in the visible and UV spectral range. This transmission can be strongly reduced by an appropriate sub-wavelength patterning of the metal film. Our investigation is focused on metal films with a thickness much below 100nm, where the transmission response is domina…
Infrared spectroscopic ellipsometry (IRSE) was applied for characterization of porous silicon (PSi) electrochemically prepared in acidic fluoride solution. When no formation of SiO2 was involved in the preparation, an anisotropic distribution of PSi bonds with the terminating molecules was achieved. On the contrary, o…
Abstract The toughening effect of ethylene‐vinyl acetate rubbers (EVM) with maleated ethylene‐vinyl acetate copolymers (EVA‐ g ‐MAH) on the nylon 1010 was investigated. The addition of 5 phr ( per hundred nylon 1010) EVM increased the elongation at break of nylon 1010 to a great extent. The notched Izod impact strengt…
We investigated magnetic and electronic properties of double perovskites ${\text{Sr}}_{2}{\text{FeMo}}_{1\ensuremath{-}x}{\text{Nb}}_{x}{\text{O}}_{6}$ $(0\ensuremath{\le}x\ensuremath{\le}1)$. As Nb substitution $x$ increases, the system gradually loses all ferromagnetic metallic characters such as the ordered magneti…
By using a true phasor approach and slowly varying envelope approximations along with Maxwell's equations and the constitutive relations in their respective domains (time and frequency, respectively), we derive expressions for the allowable propagation vector(s), electromagnetic fields, Poynting vectors, phase, energy…
Abstract Effect of mixing and processing conditions at T‐die extrusion on the structure and mechanical properties is studied for isotactic polypropylene (PP) containing a small amount of β‐form nucleating agent, N,N ′‐dicyclohexyl‐2,6‐naphthalenedicarboxamide. It is found that trigonal β crystals are predominantly for…
We construct a theory for low-energy quantum transport in $\text{normal}\ensuremath{\mid}\text{superconductor}$ junctions involving the recently discovered iron-based high-${T}_{c}$ superconductors. We properly take into account both Andreev bound surface states and the complex Fermi-surface topology in our approach a…
By using the coordinate transformation theory, we propose a media that is used to control the propagation of electromagnetic (EM) waves with the front shape and size being kept and thus to guide the wave energy along one certain direction, whatever the wave shape may be. We obtain the general formula of designing such…
C60 in der Zange: Bei Komplexen von π-erweiterten Tetrathiafulvalenen, die pinzettenartig an C60 binden, führt Photoanregung in vielzähligen Lösungsmitteln wegen der engen Wechselwirkung beider π-Systeme zur schnellen Ladungstrennung im Komplex (siehe Bild; PET=Photoelektronentransfer). Systeme, die auf ähnlichen Erke…
Abstract Bringing order : A new class of periodic mesoporous organosilicas (PMOs) with a urea‐bridged organosilica precursor under acid‐catalyzed and inorganic‐salt‐assisted conditions was obtained. The large‐pore hybrid materials have ordered mesostructure with uniform pore size distributions, which can be seen from…
The solid oxide fuel cell (SOFC), due to its high operating temperature and high fuel flexibility, may be fueled by biomass gasification producer gases. Based on the main gas components of typical producer gases (CO, CO 2, H 2, H 2 O, N 2, and light hydrocarbons), the expected SOFC performance will be in the range of…
Molekulare Wirtschaft – vier aus einem: Nanoskalige Bänder, Röhren, Vesikel und Plättchen bilden sich durch Selbstorganisation einer einzigen kovalent verknüpften Einheit auf Basis eines amphiphilen Perylendiimids, das mit einer Terpyridineinheit funktionalisiert ist (siehe Bild). Die Vielfalt erklärt sich mit einer K…
Witherite (BaCO 3 ) crystals have been synthesized by mixing BaCl 2 ·2H 2 O and NaHCO 3 aqueous solutions; their growth morphology is characterized by single and twinned individuals both [001] elongated and limited by {110} prism and { hhl } bipyramids. When quartz single crystals are used as substrates, heterogeneous…
Abstract The morphology, microhardness, and electrical properties of composites consisting of conductive polypyrrole (PPy) dispersed into a nonconductive polypropylene matrix (PP) as pure component or in form of a sodium montmorillonite/PPy (MMT/PPy) composite have been studied. For comparison, also PP/MMT composites…
The Center for Eukaryotic Structural Genomics (CESG) is a "specialized" or "technology development" center supported by the Protein Structure Initiative (PSI). CESG's mission is to develop improved methods for the high-throughput solution of structures from eukaryotic proteins, with a very strong weighting toward huma…
Salts, polymers, and organic precipitants commonly used to crystallize proteins share the ability to induce attractive protein−protein interactions, and eventually lead to the formation of crystals. Their effects on protein phase behavior are investigated here. First, the ovalbumin phase diagram at pH 7 was determined…
